Joshua 16:6 (KJV)

So the children of Joseph, Manasseh and Ephraim, took their inheritance.

And the border of the children of Ephraim according to their families was thus: even the border of their inheritance on the east side was Ataroth–addar, unto Beth–horon the upper;

And the border went out toward the sea to Michmethah on the north side; and the border went about eastward unto Taanath–shiloh, and passed by it on the east to Janohah;

And it went down from Janohah to Ataroth, and to Naarath, and came to Jericho, and went out at Jordan.

The border went out from Tappuah westward unto the river Kanah; and the goings out thereof were at the sea. This is the inheritance of the tribe of the children of Ephraim by their families.
